' IMPROVED EQUALIZBR POR VEHIGLES.

To ALL wHoM IT MAY coNcERN:

Be it known that I, J. J. CONNELLY, of Chicago, in the county of Cook, and State of Illinois, have invented Va new and useful Improvement on Equalizers for Vehicles; and I do hereby declare that the following is afnll, clear, and exact description thereof, reference being had to the accompanying drawings, and the letters marked thereon, making a part of this description, in which- Figure 1 is a plan view of my invention, as attached for use.

Figure 2, a rear elevation of the evener, showing the position of the draught-chains and pulleys.

The nature of this invention consists in the use of an evener, which has a double pulley at the centre, and a single pulley at each end, and in draught-chains arranged on said pulleys, in such a manner that each chain shall fasten to the outside trace of one horse, and to the inside trace of the other, by which means a perfect equalization of' dranght'is secured without any motion ofthe everier, as hereinafter shown.

In order to give a correct understanding of my invention, I have marked corresponding parts with similar letters, and will now give a detailed description.

B represents the tongue, and

C a broken view of the axle of a common 'wagon, to which my device is attached.

A A represent the evener, which is made of two pieces of hard wood, of suitable size and length, and their inner ends are irmly secured together by means of two plates of iron, D E, bolted through and through, as shown at i'igs. 1 and 2, but leaving room enough between said ends for adjusting the pulleys H J between them, and in the centre of the evener.

An iron plate, K, is put between the pulleys H J, as shown at iig. 2, and ltted into the inner ends ofthe pieces A A, and fastened with bolts, or otherwise,'as most convenient, the object of said plate-being to prevent the chains N O from coming in contact with each other, and also to permit the pulleys H J to operate iudependently, and turn in opposite directions.

The evener is held in position on the tongueB'by mueans of a holt, R, which also passes through the pulleys, and holds them in position.'

The end pulleys-G I are held in place by means of straps of iron, M Ii, bolted fast to the pieces A A and bolts df, in the usual manner.

A draught-chain, O, is adjusted on the pulleys G and H, and one of its ends is hooked, or otherwise fastened, to an outside trace, P, of one horse, and the other end to an inside trace ofthe other horse, and the chain N is adjusted on the .pulleys I and J, and one ofits ends is fastened to an outside trace, Q, and the other end to the trace T, by which means, if one-horse slackens the traces T P, the traces U Q will be lengthened to :the same extent; and it does not affect the equalizer in the least, by any swaying motion which the horses .may have.

This invention differs essentially from the patent granted to H. 'B. Hale and T. Flagger, March 10, 1868, in the following particulars: They use a single pulley at or near the centre of the evener, over which pulley the inside traces of both horses are put, said traces being practically an inside and independent attachment for the horses. The outside traces are also an independent attachment, passing over pulleys at the endsof the evener, thus making separate draughts for the outside and inside shoulders of the horses; and, as a result, if they (the horses) sway outwardly, the outside traces'are loosened, and the whole load is thrown upon the inside shoulders of the horses, and when they crowd the tongue closely, the load is thrown upon the outside shoulders, the inside traces being loosened.

It is the object of'this invention to'obviate the objections resulting from the use ofthe above-named inven tion, and also to provide a cheap, convenient, and uniform equalizer, which can be readily attached to avehicle, or used for general draught purposes.

It is not thoughtvnecessary to enter into a lengthy statement of the advantages gained by the use of my device, as the description clearly shows both merit and invention. This invention diers essentially from any device nowin use for a similar purpose, inasmuch as a perfect equalization is secured, even with a stationary draught-bar, and consequently each horse is compelled to bear half of the burden, or be drawn back on the vehicle.

Having thus described my invention, what I claim, and desire to States, is

A draught-equalizer, consisting of an evener or draught-bar, A A., pulley, H I G J, and chains, O N, the

chain O passing over the pulleys H Gr, and providing a draught-attachment for the outside trace ofthe nigh secure by Letters Patent of the United horse, and the' inside trace of the olf horse, and the chain N passing over the pulleys J I, and `providing-a draught-attachment for the outside trace of the off horse and the inside trace of the nighf horse, substantially as and for the purpose specified and shown.
